To all 4whom imag concern:

Be it known that- I, FREDERICK NV. COLE, of Newton, in the county of Middlesex and State of lylassachusetts, have invented anlmprovement in Supervisory Signal Sysand also by the fire signaling-devices tems, of which the following is a specifica- The invention also comprises other signalt1on. receiving devices, such asa signal-recorder,

This invention relates to an electric superlocated at the supervised building, as, for visory signal-system.

It comprehends essentially the combination of an auxiliary lire-alarm and a Watchman`s supervisory signalssystem.

lAn auxiliary tire-alarm, as ordinarily I constructed, comprises essentially an elec-l tric-circuit, auxiliary to the fire-alarm cir4 cuit, and arranged throughoutI a building or other property to be protected, and is connected to the starting-magnet. of a tire-alarm signal box in said re-alarin circuiti, and has.I signaling-devices arranged throughout the' building, adapted to be operated 1n case of a tire to cause said starting-magnet to re-v lease or otherwise operate said firealarrn box to send its signal to the {ire-department.

A. watchman`s supervisory signal-system,' as ordinarily constructed, coi'nprises signaling-devices arranged throughout abuilding controlled by .Lic watch signaling-devices and also by t. e tire signaling-devices.

A simple arrangement for sending the signals to the supervisory-station` comprehends the employment of :l supervisory-circuit connecting the supe. iscd building with the supervisory-station, and a code-signal transmitter at the supervised building, arranged to send signals over said'circuit and vadapted to be controlled by the aforesaid signaling-devices. The arrangement, however, is such that the operation of the watch signaling-devices Will not atleet the startingmagnet of the auxiliarized ire-alarm box.

This inventionalso comprises automatic. means for starting the supervisorywsignaltransmitter aft-cr a prolonged period of time, unless re-set, which is prevented from starting said transmitter within prescribed periods of-time b v tue operation of the rea watchman going his round, to control the operation of signal-receiving devices located at a supervisory-station, where supcrz visors are in attendance, whose duties are to.- note the reception of signals indicating the proper and also improper operation of the signaling apparatus, and to immediately malte an investigation in all cases of evidence of trouble, or failure of the. watchman to properly. perform his duty.

The essential object of this invention is to combine an auxiliary tire-alarm with a watchmans supervisory signalsystem, whereby the same supervision may be given to the auxiliary tire-alarm apparatus and circuits as is given to the watcbmaus signaling-apparatus and circuits; and, in addition thereto, to provide other noveiland valuable features whereby the utility, etticiency` and value, of both are increased, taken separately or collectively.

The invention comprises signaling-devices arranged at signal-stations throughout a building to control an auxiliary-circuit, and adapted to be operated at frequent in tei-vals by a watchman going'his round, to

naling-devices, whereby, in case said signal- .riods of time, in a prescribed order, or otherwise, or in case'the signaling-devices or the' auxiliary-circuit or system containing them is out of order, so as to render their operation inetl'ective, a signal, herein termed an oit-duty signal, and which is different from the aforesaid signal, will be sent promptly by the supervisory signaltransmitter to the supervisory-station, to be recorded and audibly announced.

The invention also comprehends the employment of means for controlling the operation of the supervisory code-signal transmitter to cause itto send a signal to the supervisory-station promptly, in case the auxiliary-circuit or apparatus is out of order, or is not in its proper operative condition. thereby affording a substantial element ot' safety by indicating that the apparatus is continuously in Working condition. rl`he signal thus sent. which is caused by improper or abnormal conditions, is herein Vwhich is controlled by said signaling-devices setting means, controlled by the watch sig-v ing-devices are not operated within such pe.

instance, in the ottice thereof, adapted to be as the failure to operate the Watch signaling-devices also causes signal-receiving apparatus at the supervisory-station to respond,

a valuable surveillance over the auxiliarycircuit and apparatus is obtained, which is an important feature, as it insures said circuit being kept in working condition for the sending of theV tire-signals, which ar'e the most important signals of all. local annunciators may also be employed :t'or indicating the locality of .any station operated for tire, and bells to give local alarm operated throughout the premises to call attention, and lamps lighted throughout the building.

As it is important to distinguish the signals one from another at the receiving-station and to call attention to the important signals, the supervisory code-signal, transmitter is constructed and arranged not only to send dililcrent sie'nals` but also a ditler- .supervi sory-station,

entiatin'g-impu-lse in conjunction with some vof them, which will cause the operation of alarm-mechanism at the supervisory-station, which does not respond to the other signals, and which will either audibly or visually ycall the attention of the supervisors to the fact that an important signal is being received, which requires immediate atten-- tion, andthe signal sent will depend upon the particular means which caused its operation. A number of supervised buildings will be connected with the one central or each buildingbeing equipped with van auxiliary fire-alarm system having an auXiliarized fire-alarm box and also a supervisory signal-transmitter, and the supervisoryor transmitting-circuit which extends from the supervised building to the supervisory-.station will include the supervisory signal-transmitters of two or more supervised buildings, and therefore the supervisory signal-transmitters are preferably provided with signaling-devices` Whereby code-signals Will be transmitted by each for the identification of the supervisorytransmitter from which the signal.v is sent, and they interfering devices controlled by the transmitting circuit, `zvhereby confusion' or loss of signals is avoided, they being of such a nature that no matter for which one ol" itsl several signals the signaling-mechanism has been set to transmit, the noa-interference Suitable.

will also be provided with nondevices will keep it so set until the selected signal has been correctly sentover the trans-- mitting-circuit.

Figure lis a diagram .of a circuit which may be employed in' installing' the system embodying my invention, the several devices which are connected therewith being also shown in diagram, Fig. 2 is a front view ot avmultiple code-signal transmitter, such as may be employed, Figs. 3 and 4- are respectively front and side `views of the onduty and the oit-duty signal-controllin r mechanisms which may be employed, Fig. 5 is aA front view. of a Watch-clock such as may be employed, the on-duty and ott-duty signaling-mechanisms being arranged in, the case thereof, Fig. G is a side view oi a relay which may be employed to control the circuit to send a fire-signal and also a testsignal, Figs. Tand 8 are details of the annunciating means which may be'enniloyed for locally annunciating the fire-signals.

The auxiliary-circuit here shown, see Fig. l, for the purpose of illustrating this invention is a modification of a well-known type, and comprises essentially an open circuit having a heavy battery and one or more open vbranches at 'one side of said battery and a closed loop at the other side of said battery.

a represents the heavy battery; fz', a2, the circuit-Wires of the closed loop at om` .side of said battery; and a a circuit-wire leading from the other side of said battery which has one or more open branches at. A sin-all attery a5 may and preferably will be arranged in the closed loop for testing purposes. The closed loop is extended tlir'uigliout the building or other property to several fire-signal stations Z), and also to an auxiliarized lire-alarm box a, the start-ingmagnet a7l of which is contained in said loop. The auxiliarized fire-alarm boxhas its signaling-devices connected in a tir Valarni circuit by which the fire-alarm signals are sent to the tire department vAt the several auxiliary lire-signal stations b, as represent pivoted switch-arms normally resting on plates f1.9, all arranged in series in the closed loop. The several open branches a4 of the auxiliary-circuit also extend to thel several auxiliary fire-signal stations I), and are connected to plates nl", arranged close to the plates a9, so that the switch-arms as may be readily moved trom the plates (L9 to make connection with the plates al. The switch-arms as and plates a, a constitute the tire-signaling devices, and said signaling-devices are manually operated', and, When operated, theclo'sed loop Will be opened, and that,side ofV said loop containing the starting-magnet a7 of the auxiliary tira-alarm box Will be connected to the open branch leading to the plate al associated with the switch-arm which is l operated. The heavy battery a will be'then included in the circuit thus formed, and the starting-magnet a7 caused to release -or otherwise operate the auXiliarized fire-alarm box. Incase the usual small battery a5 is employed in the closed'loop, it- Will preferably be arranged with its poles disposed thesame 'as the pol-es of the heavy battery a., so that, when the two batteries are connected 'n series, their combined energies will be utilized.

Throughout the building Watchinans signal-stations hereinafter' Watch-signal stations or Watch-stations are arranged. They maybe combined with the fire signal-stations b, but preferably Will be made as separate stations. As here shown, they each have a signaling-device, such as a circuit-closer ZJ', adapted to connect together' a pair of circuit-Wires. b2, b3, one, as b2, leading from the closed loop of the auxiliary-circuit, preferably from one side of' a tire signaling-device and through a resistance-coil Z2, and the other, as b, leading from a branch a* of the auxiliary-circuit,

preferably from the plate a, which is electrically connected with the plate am at the other side of said fire signaling-device.

The circuit-closer b may comprise a key, which will be carried by a Watchman, having projections designed to engage and connect together tivo pairs of spring-clips connected respectively With the circuit-Wires b2 1o3. Whenever any one of the Watch sigv.. nahng-devlces 1s operated, one of the open branches a4 is connected with the closed loop, forming a closed circuit as follows: battery a, circuit-Wires a3, a4, b3, signalingdevices b', circuit-Wire "b2,'to the closed loop,

Where the current divides, the` larger part going through the path of low resistance by circuit-Wire a2 to battery. Thus, a section of the closed loop and some one of the branches of the auxiliary-circuit is utilized when operating any of the Watch-signaling devices. If one of the sections of the closed loop should be broken at the moment the signaling-device b is operated, the other section will be utilizedy to form a Closed circuit. The resistance b4, which is included in the circuit formed bythe operation of the watch signaling-device b', as, for instance, in branch-wire Z22, is sutiicient to allow but a small amount of current to flow through the circuit, so that the starting-magnet a? of the auxiliarized fire-alarm boX will not be operated to start said bmx, even though the section a2 of the loop is broken and the section a of the closed loop is. the only one included in the closed circuit formed by the operation of the Watch-signaling devices.

The Watch signaling-devices are designed to control the operation of signal-receiving.

-qupervisory-station 1.00,

apparatus at a attendance, and

Where the supervisors are in referred to as 3 means are herein provided for sending t0 said supervisory-station two different signals Which are controlled by the Watch-signaling devices, namely, an on-duty signal, indicating that the watchman is attending to his duty, and an olf-duty signal, indicating that the Watchman is notattending to his duty, or that, for some cause, the Watch signaling-devices or circuits or devices responsive to the operation thereof have failed to operate. These signals coming into the supervisory-station place the 'i Watchman andthe signaling-devices and the circuits controlled thereby, including the auxiliary fire-alarm circuit, under the direct supervision of the supervisors at said station.

For sending the on-duty signal the means shown in my application for Letters Patent, SerialNo. 555,603, filed April 15, 1910, may be employed, and such means possesses many advantages, among them being the provision of means for requiring the Watchman to visit the signal-stations in a prescribed order, and also means for locally recording all the signals, and means for sending a signal. to the supervisory-station only when all of the signal-stations have been visited. In lieu of this particular means for sending the on-duty signal, so far as my present invention is concerned any other suitable means may be employed.

For sending an olf-duty signal, the means shown in my application for Letters Patent, Serial No. 555,604, tiled April 15, 1910, may be employed, as such means possess many advantages, among them be` ing the provision of auto-matic means for sending a signal after a prolonged period of time, unless re-set, and re-setting means adapted to be operated by the signalingdevices at the signal-stations when said signaling-devices are opea'ted to send the onduty signals. In lieu of this particular means for sending the off-duty signal, so far as my present invention is concerned any other suitable means may be employed.

Both the on-dut-y` and the ott-duty signaling-means are designed to operate or set in motion suitable code-signaling-mechanism for sending signals over a supervisory circuit 101, to a supervisory-station 100, and for sending these two signals, as well as other signals as Will be hereinafter described, code-signal transmit-ting means, such, for instance, as shown in my application for Letters Patent, Serial No. 555,C05, tiled April 15, 1910, may be employed, but my invention is not limited to the employment -of these means, as it is 0bviousv that, so far as this invention is concerned, any other suitable code-signal transmitting means may be employed. The particular formof code-signal transmitting-i means shown in my said application consists of a multiple code-signal transmitter, and sends its signals -over the supervisorycircuit 101, to the supervisory-station 100.

-Referring to Fig. 2, the multiple signaltransmit-ter of my said application is shown for purposes of illustration, but a detailed description of the same is deemed unnecessary. The signal-wheel m20 of said transmitter is adapted to co-act 'with a signalkey m21, and to be revolved to send a codesignal representing. an identiication number of a supervised building withor without a differentiating signal-impulse. The signaliinpulses composing the identication number are of short duration, and the diiferentiating signal-impulse is of long duration. The identification number, once sent, designates the on-dutv signal; twice sent, with' a differentiating signal-impulse between them, designates an off-duty signal; and, as additional signals which may be sent' by the transmitter andv which will be hereinafter described, the identiiication number three times sent, with diiierentiati'ng signal-impulses between them, designates a trouble signal; and :tour times sent, with di'ilierentiating signal-impulses between them, des-l ignates a fire-signal. The prolonged signaliinpulse is caused to be sent with all the signals excepttlie con-duty signal, and `is prevented on such signal by the coperatio'ii of a pivoted lever n with the signal-key m21, said lever being moved by a cam-disk n2, revolving in v unison with the signalwheel. This signal-transmitter is adapted to be electrically started and controlled, and, for such purpose, a starting-magnet m16 is employed for releasing or otherwise operating it, and also for cont-rolling its operation w to cause` the different signals to be transmitted. Said starting-magnet m16 is connected in the circuit of battery d, and said circuitl has several branches containing circuit-controlling devices, arranged toy separately control the operation of said circuit and thereby cause the starting-magnet to release the signal-transmitter to transmit the different signals. This local circuit is controlled by relays in the branches ofthe auxiliary-circuit, but, said relays may be omitted if desired. As several code-signal transmit-ters are designed to be included in 'a single supervisory-circuit which is connected with a supervisory-station, each may be provided with non-interference devices adapted to be controlled Aby the supervisory or transmitting circuit, whereby confusion or loss of signals is avoided; as, for instance, a non-interference magnet m40 may be einyployed, see Fig. 2, the armature m41 of which is attached to a lever'm adapted to coperate with the signaling-devices in the manner shown and described in my said applicat-ionJ Serial No. 555,605. For thetransmissi'on of an ,on-duty signal a local cirdevice f, circuit-wires f3, f2, j, d2, to battery.

Herein said local circuit-controlling device f is adapted to be operated when, but not until, the signaling-devices of all the watch signaling-stations have been operated, pref- -erably in a prescribed order. For the accomplishment of this result the on-duty signal-mechanism of my lapplication Ser. No. 555,603, is herein employed, which is slio-wn in Figs. 3 andv 4, for purposes of illustration only. A detailed description is herein deemed unnecessary.

Referring to Figs. 3 and 4, e represents the controlling-magnet for the route-determining mechanism, aiid e, e2, c, thc routeswitches corresponding in number to the,

number of watch-signal stations.. Said switches are arranged in separate branches of a local circuit controlled i'espectivelyby the several watch signaling-devices, aiid'ftlie controlling-magnet is arranged in a branch common to all said branches, whereby it may bel arranged in series with any one of said switches. As ,here shown, see Fig. 1, the several switches are included in branchcircuits (ZB, d, leading from a branch-circuit all, which is common to all said branchcircuits d, and contains the controllingmagnetl c. Said branch-circuits (Z8, (Z9, re-

spectively extend to the contacts d10, withv which the armatures b of relays b5 are adapted to coperate. Said armatures b ,are connected by circuit-wires (ZGwith-the branch-wire Z3 of the local-circuit, and the relays .b5 are included in the open branch-` wires a* of the auxiliary-circuit, so that said armatures are respectively responsive to the operation of the several watch signaling-devices' ZJ. The, local-circuit containing the route-switches is as follows: battery'dfcircuit-wires d', cl3, armature'a23, of a testingrelay (to be described), circuit-wires'd, d?, d8, (Z9, contact d1armature be', circuit-wires d6, d3, d2, to battery. But one of the switches is closed at a time, andthe controlling-magnet can only respond to the operation of the particular watch signaling-device which' controls the branch-circuit containing the closed switch, and it is designed that the switches shall be successively closed by means controlled by the controlling-magnet e, to place said controlling-magnet successively under the control ofv the several watch-signal-stat-ions to be operated by the signaling-devices thereat and to thereby re` quire the watchman to visit the several signal-stations in a prescribed order; that is to say, a-s'a'closed switch is opened, the next succeeding switch will be closed, and so on throughout the entire group, and the constations, the intermittently-movable route-` trolling-magnet c is therefore successively arranged in series With the switches. For the purpose of successively,l operating the several switches seriatz'm, as'above described, a series of fingers e7, see Figs. 3 and l one for each switch, extend radially in different directions from a shaft and said shaft is t adapted to be revolved intermittently to cause the fingers to successively engage fthe switches. Said. shaft is normally atl rest with one of its fingers in engagement vvithl one of ythe switches, to thereby hold said switch closed, and, as the shaft is moved,`

said finger disengages its switch, and the next finger engages its switch, and so on during theentire revolution of the shaft. A normally-Wound train is employed for revolving the shaft adapted to be released' by the controllingmagnet c each time said magnet is energized.

Said magnet, hovvever,can onlybe energized as stated, by the operation of a signalingdevice which 'controls the i branch-circuit containing a 4closed switch 1n series With' Whlch said controlling magnet 1s arranged.

"When all ci the route-switches c', etc.,

have been operated, as a consequence of the Watchman visiting all of the watch signalswitch mechanism will have completed a cycle of its operation, and, at such time, or during one of its steps, the local circuit-conltrolling device f will be momentarily operated by it. To accomplishY this result, an arm et", loosely mounted on a pivot-shaft 64.1 is arranged to engage said local circuitcontrolling device f, and an arm c, which is also mounted for convenience 0n said pivot-shaft c, has a laterally-extended pin c, which engages said arm 640,' and an arm ett-is connected with said arm 642, and extends into the path of movement of a pinv e on the gear-Wheel 623, or other movable part ofthe train, so as to engage said arm c While the shaft es is moved duringone of -i'tsintermittent movements.- yWhen the pin c45 in passing engages and moves this arm' ci the local rcircuit-controlling device f Will be momentarily closed to cause energization of the starting-magnet m16 of the supery visory signal-transmitter, to merely release said transmitter to permit it to operate and send its f on-duty signal. When the starting-'magnet m15 is thus energized, the locking-lever controlled by it is moved to release the-signal-transmitting train; that is to say, the arm m14 of the locking-lever disengages the detent m13, but before said detent m13 has made a complete revolution the varm m3 of the locking-lever Will be held inunlocked position by the notched `disk ma, and, as' the starting-magnet is immediately denergized, said .locking-lever will be permitted to resume its normal position, as

soon as the disk ma has made a complete intermittingly, Awhich isties,

,connected with the circuits revolution, at which time a pin m32 on the arm m33 falls into a notch i n said disk. As the signal-'Wheel m20 is secured to the shaft mtfvbearingthe notched disk ma", it also makes a complete revolution during this time, and a signal, consisting of one round of the identification number, is transmitted. Each time a watch-signaling-device is op'- erated, the auxiliary-circuit, or at least a supervisory-station and have not been tampered With-,or disabled from any cause.

As a local means for recording the movements of the Watchman and the time he visits. the several Watch `signal-stations, an electricsignal-recorder, such as Watch-clock, may be employed. Said signal-recorder,

. imay be located -in the building to be supervised. It may be of any usual or suitable construction, so far as my present invention is concerned. In Fig; 5 an ordinary Watchcl'ock is shown as the signal-recorder for purposes of illustration` only, and in the case ofsaid clock the t on-duty 'and olf-duty signaling-mechanisms and other devices are preferably located, in order that as much as possible of the apparatus may be assembled in compact form. The Watch-clock has several operating-magnets c corresponding to the number of Watch-signal stations. Said operating-magnets c are included in circuit- Wires .d5 leading from the circuit-Wire d4 to the circuit-Wires di, so that they are arranged respectively in multiple with the leading to thel route-switches c', etc., and are adapted to respond to the movements of the armatures of the relays b5, regardless of Whether the route-switches e', etc., are open or closed.

Asthev Watchman visits the several Watch i signal-stations and operates the signalingdevices thereat, the operating-magnets c will be operated and the Watch-signals recorded ,on the dial of the Watch-clock, thereby in,-

dicating that he has visitedhis stations, and also the stations he has visited,'and the time of each visit, even though the route-switches have not been operated or have failed to respond, for. any cause, or the on-dut-y signal has notA been sent. In case the Watchman "should not follow the prescribed order, such error, or the route he did follow, will be recorded on th'e dial of the \v: Ltch-clock, a d therefore serve as an additional check on the watchman. This watch-clock also serves as a local recorder' for the auxiliary fire-alarm signals, for, whenever one of the fire-signaling-devices is operated to control the'auXiliary-circuit and cause the starting-magnet a? to release orotherwise operate the auxiliarized fire-alarm box, a relay b, corresponding to the lire-signal station which has been operated, will attract its armature, and

at work, or before they can escape, for'the mamtenance of the high eiciency of the' the re-alarm devices1 auxiliary-circuit and connected therewith, as well as for maintaining proper supervision of the Watchman.

0 In Figs.V 3, 4, and 5, the means employed in my said application Ser. No. 555,604, are shown for sending the off-duty signal, but a detailed description of4` same is deemed unnecessaryl l it representsa local-circuit-controlling device, which is shown as normally open, and, when closed, operates to close branches of a local-circuit to operate-the starting-magnet m1 of the supervisory signal-transmitter' and cause said signal-transmitter to transmit the oli-duty s1gnal..-.Said. local-circuit is as. follows,'see Fig. l: battery d, circuitwires al', d, starting-magnet m1", circuitwires d", f4, f5, circuit-'controllingdevice t, v circuit-wires f2, f d, to'battery.v

' Automatic means is provided for operating the local circuit-controlling device h, to close the. local-circuit, at the-end of or after a prolonged period of time, and said automatic means is arran ed to be repeatedly-reset or set back to startmg point on each operation of a watch-signaldevice b', and, as here shown, onthe operation ofthe route-switch mechanism, although any lsuitable vmechanism responsive to the' proper operation of signaling-devices at the watch-signal stations may be employed, in lieu thereof. As the watch signaling-devices are operated at frequent intervals, to properly operate the route-switches e, etc., and

finally send the on-duty signal, said automatic means will be repeatedly re-set and hence will not operate said circuit-controlling device 71.; but if more than time expires during which a watch signal.-

The local circuit-controlling device I1, may comprise a pair of contact-pens, see Fig. 3 which are normally separated, one of which is movable into engagement` with the other to close the circuit by its own spring action, when permitted' to act'.

Ari-arm it', pivoted at k2, is provided for normally holding said local circuit-controlby engaging the springacting contact-pen. Said arm is moved in one direction, or advanced by the pressure of the spring-acting contact-pen upon it, but such movement is controlled or retarded by `a continuously-operating timing-mechanism,

such as a clock-train, and said arm is moved in the opposite direction or set back to starting oint or thereabout by means controlled by t e controlling-magnet c for the routeon-duty signalingdevice. C y y Thetiming-mechanism for timing or retarding the forward motion of the arm It', as here shown consists of a winding-shaft h1", see Figs. 3, 4 and 5, bearingA a mainspring, a spur-gear k12 driven thereby, which engages and drives continuously a pinion 7a2? securedto a shaft A,and a ratchettoothed wheel "liza is secured to said shaft hf. i

Said having a pin ha", which engages a pawl [1f-5, pivotally supported on -another arm it, mounted loosely on said shaft h5. The pin LG. enters or extends through a slot in the pawl, which is arranged at the side of its pivot, so that the pawl is movable on its pivot into and out of engagement with the ratchet-wheel by a movement of the arm 71.",

to thereby connect the arm L with and disconnect 1t from the continuously-moving ratchet-wheel. lVhile the pawl is 1n engagement with the continuousl f but slowly moving ratchet-wheel, the arm [L24 and pinion /L connected with it are moved slowly in a direction to permit forward movement of the arm z, and, if said arm. h for a prolonged period of time, it will move forward far enough to permit the springacting contactpen to engage the other pen and thereby close the circuit. To insure a quick closing of the members of said circuitcontrolling device 7L, as contrasted to a slow closing ofsaid members, incident to the slow to thereby prevent the battery from running down while a good is connected to aniarm het,

said magnet will release or cause the off-duty Y signal. this signal, the

contact is being made, means are provided for disengaging the pawl from the ratchet-` wheel at or about the end of the allotted pe` riod of time, whereby the arm k' is thereafter unrestrained. To accomplish this re-v sult the pawl is provided with an extension l or tail h, which at the proper timeengages a ixed pin has on the' frame and by said pin is turned on its pivot lto disengage the ratchet-wheel, and said extension is made` long enough to continue in engagement with said pin hes while the pawl is' thereafter moved forward farther, and also while it remains in such forward position to allow quick closing of the contact springs h.

When the circuit-controlling -device h closes the circuit of thestarting-magnet m1, the supervisory signal-transmitter to operate to send When transmitting signal-transmitter will continue to operate until the circuit of the starting-magnet' m16 is opened. As here shown, this result is accomplished by means controlled by the signal-transmitter and non-interference magnet, as, for instance, it. may be accomplished mechanically by a cam-wheel h4 driven by the transmitting mechanism, which operates when the identitcation number has been twice correctly sent, to raise a pivoted lever h, which is connected by a rod h with one end of a lever 11.43, pivoted at ai.. The other or outer end of said lever 71,43 is beveled at one side and adapted, when depressed, to engage a pin't45 on the arm k to move said arm backward a short distance, far enough to open the circuit-controlling device h. The

arm h is then partially restored to normal lThe lever h re-set.

its outer end, which position, or partially has a shoulder h at Ipasses by and slips under the pin h4, when moved as above described, and by engagement with said pin bot-h said lever and the arm h are locked relatively to each other.

f f The lever isv at such time prevented from les returning to normal position and the arm h is held with the circuit-controlling device h Y lh43 has a loose sliding conopen. The lever nection with its actuating-mdk, so that,- when moved by said rod to open the circuitcontrolling device h, it may remain in such abnormal position until subsequently released, yet the rod hf*2 is permitted to return to its normal position independently thereof. As the arm k' is thus moved backward a short distance, the arm 71,3 is correspondingly moved and the pinion revolved and the arm h moved backward, carrying with it lthe pawl and pawl-carrying arm, butthe pawl is still held disengaged from the ratchet-wheel, and not unt-il after the arm h2* has been restored to normal, and is beginning its forward movement, will said pawl again engage the ratchet-wheel. This automatic- 4starting-means for the signaltransmitter is as above described thus tem- ;porarily disabled, or thrown out of action. .For the purpose-of setting back the arm JL- to starting point by means controlled 'by the switch-controlling magnet e at any time during its' forward movement, to the circuit-controlling device h from closing the circuit, fand .also after it has permitted the circuit-controlling device to close the circuit and has subsequentlyl opened said circuit-controlling device, an arm he is rigidly connected with said arm h', and is loosely connected by a rod k7 with a springactuated arm hs, pivoted at k, and arranged to normally rest upon and be held in elevated position by any one of the teeth o'f the intermittently revoluble ltoothed wheel e30 connected with the route-switch mechanism. When said toothed Wheel e30 is revolved one passes from beneath the arm, permitting the arm to be moved by its actuating-spring into the interdental space adjacent said tooth,

and suchmovement of the arm will cause the rod hl to draw down the arm and move the arm h toward the left andi-hereby re-vset it. Before the toothed wheel e30 is arrested, the next tooth thereon willen gage an'd lift the arm hS and rod k7, but during such upward movement said rod will slide freely in the hole in the arm h through which it passes. When the arm k is thus re-set the sector-lever isl re-set by it, also the loose pinion h4. and arm connected with it, and the pawl is caused to pass over. but free -from the teeth of the ratchet-wheel during such re-.setting movement, but said pawl is moved immediately int-o engagement with. the ratchet-wheel by the beginning ofthe forward movement .of the arm hn. The exit by and during greater than the length of the periods of must be successively visited by the watchman, and such movement and prolonged period ot time may be adjusted by a stop h3, arranged on the frame against which the arm h3 When the watchman goes ott dut-y, say in the morning, the off-duty signal is soon sentvautomatically by reason of the. watch signaling-devices not having been operated during a prolonged period of time, and the automatic starting-means will not be re-se't until h e goes on duty at night. In case another watchman goes on duty when the night watchman leaves in the morning. as would be the case on holidays and Sundays, then the olf-duty signal will not be sent, and the apparatus remains in operative conprevent step the tooth on which said arm hs rests strikes when moved backward.'

tent of backward movement of the arm h2* Y time during which the watch-signal stations and means are herein provided for automatically re-setting the starting-means at a pre'- determined time, as, for instance, When the .Watchman is due to return to duty, so that,

, in case he should not return to duty on time,

mined by the indexed Wheel.

an off-duty signal will be sent. For-'the purpose of accomplishing this result an arm h5 is adjustably secured to a. shaft of the timing-mechanism, as, for instance, to the shaft ffl; and a toothed-Wheel A52 is secured to the said shaft, back of said arm, which is arranged to make a complete revolution every twenty-four hours, and is preferably indexed to indicate the hours. Said arm 7h50 may be setto occupy 'dili'erent positions on its shaft, Which positions may be deter- Said Wheel A52 is driven by a toothed-wheel IFB secured to one of the shafts of the clock-train and the arm h5 is moved by it. This arm is made long enough to en age the pin 7L when the latter is in loc ing engagement With the restoring-lever' 71,43, but Will pass by said pin lWithout engaging it when said pin `is in its re-s'etposition. In case the arm 715 engages-the pin While said pin is in locking engagement with the restoringlever It, it acts to move said pin out of' engagement With the shoulder on the restoring-lever, thereby releasing said restoring-lever, allowing the arm h5 to re sume its normal position, and, as soon as it passesA by said pin, the arm h is ,free and will be immediately moved by the pressureof the spring-acting contact-pen thereupon to permit the circuit-controlling device L to again close and cause the supervisory signal-transmitter 'to send an t of duty signal. If the Watchman has returnedto duty on time and has visited his first station, then the arm 7L Will have been re-set by the means controlled by the switchcontrolling magnete, and hence the Apin 71,45 will be removed lfrom the path of movement of the arm. An oit-duty signalingmechanism is thus Iprovided which gives a most eflicient and valuable service under many different conditions, It is adapted to be brought into, service When required, both manually and automatically, and remains in Aservice as long as required, including Sundays and holidays, and the Watchman and the property and also the auxiliary and local circuits and signaling instruments are un- .der the `same protection and supervision during Sundays'and holidays as during'the nights When the Watchman is on, duty. When not required, 'the ott-duty"7 signal is automatically sent to indicatel that the o-duty signaling-mechanism 1s pro erly` 01 in circuit and temporarily disable lvvound condition, and, for the accomplishment of this result1 the Winding-device for both trains is connected together and provided with a hand-lever projecting from the case which is adapted to be operated by the Watchman to Wind both trains at the same time.

The Winding-lever en, of theroute-switch mechanism, and the Winding-lever 172,105 of the signal-transmitter, are connected together by a bar e6, and a hand-lever m10 is Aconnected with the shaft of one of the Winding-levers for operating both Windingdevices. In case a Watchman fails towindthe trains at the designated times, means are provided for sending an 0H-duty" signal to the supervisory-station, and, for the accom-- I plishment of this result, as shown in Fig. 3,

signal-stations. Said lever is arranged so that, when moved by its projection entering the notch in the cam, its end-portion Will be moved into the path of movement of the locking-lever c25, and thereby prevent said lever from moving far enough to release t-he train, and, as a result, the arm L 'of the oli-duty circuit-controlling device 72, cannot be ,set back to starting-point, and hence Will soon cause said circuit-controlling device 7L to close and thereby cause the supervisory signal-transmitter to send an 0H- duty signal in-` the manner heretofore described.

As it is important that the supervisorystation be immediately notified .of any trouble in the auxiliary-circuit, automatic means yare provided for testing it, and said means v'1s adapted to control the operation of the 125` supervisory-signal-transmitter, whereby a signal is sent `to the supervisory-station. This signal lis herein referred to as the trouble signal, and is distinguished from Lthe other signals, as, for instance, it may 130.

' net m1, to indicate the condition ofthe auxconsist of the identification number threel times sent, preferably in connection with dis- -cause the trouble signal to be sent, con-v tinguishing impulses, whereby it is not only recorded, but also causes a visibleoraudible alarm-mechanism to respond.

For the purpose of automatically and continuously testing the closed loop a. ofthe auxiliary-circuit, a small battery a is ineluded therein, and also a relay am. The armature a of sai(1 relay is normally held by the weak battery in a semi-attracted position, see Fig. 6, against an. adjustable pin a, on a' pivoted-lever als, having connected With it a spring Whichis strong enough to resist further attraction of the armature when only the current of the Weak battery is passing through the relay-magnet. When the armature of said relay is moved into its fully retr Acted position, as from a break in\ the close loo-p or a weakening of the battery, it will engage a back contact-point al". The contact point a is connected by a branch-wire (L with a brancl`1wire fof the local-circuit of the starting-magnet m16, and the armature of,14 is connected With the branch-wire .20 of said local-circuit, so that, when the armature closes on said back contact-point a, a local-circuit of the startingmagnet m16 is closed to release .the supervisory code-signal transmitter 'to send a trouble signal to the supervisory-station. This local-circuit is as follows: battery d, circuit-Wires d', 23, starting-magnet m18, 'circuit-wires d, f4, f5, a5", contact-point am, armature a, circuit-Wires d2", d2, to battery. V

The signaling-determining device provided for controlling the transmitter to sists of a switch-opening device represented' as a cam-disk, adapted to be moved by the train to open a switch at the end of three rounds of the identification number, and. which is shown as a pair of contact-pensi, which are arranged in the branch-Wire f4 pf thelocal-circuit of the starting-magnet m1 of the transmitter. As soon as this switch is opened by the aforesaid switch-opening device, the local-circuit, which is closed by the retraction of the armature a, is opened, and the startingmagnet m1 then permitted to resume its normal condition to stop the transmitter, as previously described. The armature a and contact-point a thus constitute a local circuit-controlling device for controlling the circuit of the startingmag zal, the armature o23 of which is normally re# y `tractedl and engages a contact-point c25 connected With the branch-Wire d3 of the localcircuitof the startingwmagnet m16, and said armature, when moved into attracted position, will engage a lcontact-point a connected with a branch-Wire a, leading to the branch-wire f4 of the local-circuit. In case a cross occurs, as above mentioned, the armature o23 is attracted, as is also the arma- `ture b6 of one of the relays, thereby closing the local-circuit of the starting-,magnet mi, which includes the switch z', so that the same trouble signal as heretofore described Will be sent to the supervisory-station. The circuit is as follows: battery d,

circuit-'wires d', dzstartingmagnet m16,4

circuit-Wire d?, circuit-Wires f4, including the swltch z', circuit-wire a, contact-point a, armature o23, circuit-wires d4, el, d, contact-point d10, armature b, circuit-Wires d,

d3, (l2, to battery. It will be notedthat, in addition to the trouble signal being sent to ,the supervisory-station, a local record will also be made on the local signal-recorder, indicating the particular branch-Wire which is accidentally connected or crossed to the closed loop of the auxiliary-circuit.

The armature of and contact-point a of the cross-relay constitute a local circuitcontrolling device for the circuit of the esl starting-magnet m1, which is operated to indicate the condition. of the auxiliary-circuit and particularly the open circuit-wire thereof. The retractile-spring a2", which is connected to the .armature o23, is quite strong, and acts to hold said armature re tracted when the AWatch signalingfdevices e are operated, and a resistance bt is included,

so that said armature will not respond to.

the operations of .said signaling-devices. Therefore, it will be seen that these two local circuit-controlling devices, Which are employed to indicate theA condition ofthe auxiliary-circuit, are arranged to cause codesignals to be sent to the supervisory-station, whereby abnormal conditions of the auX- iliary-circuit lwill be immediately indicated at said station, and the particular auxiliarysystem from which the signal is sent will be identified, and, so far as my, invention 1s concerned, they may be so employed regardless of other features of t is invention, When employed in connection with the means for' sending other sup'ervis'oryssignals, the supervisory signal-transmitter will prefer'ably be of the multiple type, but otherwise iliary-circuit, and particularly the closed loop thereof. g For the purpose of automatically sending a trouble signal tothe supervisory-station in case of a, cross connecting any one of the branch-wires at of, the open auxiliary-Wire #with the closed loop w', avrelay a, called a rosarelay', is. included insaid 'cireuewire a simple form of code-signal transmitter may be employed. In the system, as here showm-thc circuits are constructed as separate, normally open circuits, but this construction is` not a material part of my invention asit is obvious that'all the circuits might emanato' from' a single source of en-- i ergy, and yet be separate as regards their an arrangement of cir- 'vice f, so .that when said local circuit-controlling device is opera-ted to close the localcircuit o-f the starting-magnet m1, said testing-magnet p Will be included, and, if Athe battery-current Z is of the requisite strength, it Will be properly energized to hold its armature inattracted position, and,

if the current is not of the proper strength, the magnet will be but slightly or moderately energized, and not enough to hold its armature in attracted position. The localcircuit containing the magnet 79 is as follows: battery (Z, circuit-Wire cZ, (F3, starting-magnet m15, circuit-Wire ft, local circuit-controlling device f, test-magnet p, (Z2, to battery, p2 represents the armature of this testing-magnet p. It is' loosely mounted on shaft 793, and has an extension on which is adjustably secured a retractile Weight p. Secured to the shaft p3 is a supporting-lever comprising a portion p5, extended beneath the armature p2, through which passes an adjusting-screw on Which said armature rests, so that the normal position of said armature is controlledy by said f, then its end Will supporting-lever. This also comprises' an arm 774, which engages or rests against the end of an arm p, connected With the arm e, which is adapted to operate the local circuit-controlling device f. The arm p4 of the supportin -lever has a notch at its end in front of thepoint of engagement with the arm p", and, when the arm p6 is moved, as it Will be When the larm e is moved to close the circuit-controlling device pass over the notched portion of the arm p4. At this moment,` if the battery-'current is of the requisite strength, the testing-magnet p will be ensupporting-lever ,efgized suiiiciently to attract and hold its armature p2 in its attracted position when released by the aforesaid movement of the arm p6; but, if not of then the armature Will be moved into its retracted position, raising the arm p, so that its notched end-portion will engage the arm p", While the latter is in its abnormal position, and the shoulder of the notch Will thereby lock said arm p from returning to normal position, and the parts will remain locked and the circuit contacts f closed until the armatures and supporting-lever have been manually restored. .o

the required strength,

y An arm p7 is secured to the pivot-shaft p3, to Which the supporting-lever is also fastened, and said arm extends in the path of movement of a Hat' restoring-spring fastened to the frame. The end of said spring is connected by a link p8 with an arm 71 on a rock-shaft p10, which may be manually turned to positively raise the link and thereby allow the spring to restore the armature. The rock-shaft p10 is provided with a restoring-spring Which is strong enough to overcome the flat restoring-spring for the armature. As the arm 7) is connected with the arm c, it will be observed that the local circuit-controlling device f Will become permanently closed when the arm p is locked by the supporting-lever, instead of momentarily closed, as heretofore described, and such permanent closure operates the starting-magnet m1 tb release the silpcrvisory signal-transmitter, and continues to vthus hold said starting-magnet while said transmitter operates until the signal-determining device of said transmitter operates to open the switch vf, and the signal sent Will there- Afore be a trouble signal. The circuit of the starting-magnet m1 in such case is the circuit which is opera-ted by the local circuit-controlling device f, before-described. Thus, notwithstanding this local circuit is normally open, it will be frequently tested, and, if it is found that the battery l is not of the required strength, a signal Will be sent lto the supervisory-station, notifying said stat-ion of the fact, in order that a supervisor may be sent to the building at once to correct the trouble. Similar means may be provided for testing the open-circuit bat- -cry aof the auxiliary-circuit. as for instance, another magnet and armature are arranged just back of the ones shown and another pair of contacts in circuit with said magnet, arranged to momentarily close a branch from the open auxiliary circuit through such magnet and a proper resistance simultaneously with the closure of the circuit-controller f, and if the current from the auxiliary battery is Weak then the armature of its magnet will fall at such time and causethe supporting-lever to lock the contacts f closed and give the trouble call as before stated. Means are also provided for sending a trouble call in case the main-spring of the route-determining mechanism should break, which consists of an arm e50 connected to the arm e4". This arm @50 lies in the pat-h of the main-spring, and, if said spring breaks, it will immediately expand and engage 'and move said arm e, causing the arm @4 to close and hold closed the contacts to thereby send the trouble signal as previously described.

It is desirable that the manual fire-signals due to theogeration of any of, the fire-sig-A naling devices nthe auxiliary-circuit, and

which are adapted to operated the .auxiliarized fire-alarm box, shall also be sent to the supervisory-station; to thereby', notify the supervisors at said station of the manual operation of the auxiliary-circuit at the supervised building, and, consequently, the

' '15 of this relay normallyoccupies a semi-attracted position, bearing against an adjustable pin a, borne by a pivoted-lever als. This lever@18 lhas a shoulder al?, which is normally .engaged by a pin a extended laterally from a spring-operated lever a2", pivoted at a2, and locks said lever a2 in set position. The pin at24 also extends beneath a contact-pen a, and, when the lever L20 is released by the lever als, upon the arma- 25 ture being moved into its fully attracted position by a heavy current passing through its magnet, said pin a24 will engage saidv pen a, and close the circuit. The pin a24 will remain in engagement with the contactpen a unt-il manually re-set. Vhenever any 'of the manually-operative tire-signalingdevices are operated and the starting-magnet of lheauxiliarized b ox thereby caused to release said box, the armature a of the relay L13 will also be moved into its fully at-l tracted position, resulting from the heavy current whichi will then pass through its magnet. The circuit-controlling device a24 and a21 4o is". connected in branch-circuit-wires d, a, d2?, of the circuit of the battery d, and, when closed, the circuit of the starting-magnet m1 is'closed to cause said magnet to release the supervisory signal-transmitter. Said cir- 46 cuit is as follows: battery d, circuit-Wires d', .6123, starting-magnet m16, circuit-Wires d22,.cl.21, circuit-controlling devices a, am', circuit-Wires (L52, d20, switch 7c, circuit-Wire d2 to battery. Vhen the circuit-controlling` 50 device a, a, is closed, the armature of the starting-magnet m Willbe held in its attracted position until the circuit, including said v'circuit-con-trolling device, is opened, and,to accomplish this result, another sig- .55 nal-determining device operated by the supervisory signal-transmitter is employed for opening this local-circuit. Such signaldetermining device comprises a switch-opening device operated by the transmitter and adapted, tooperate a switch k when the A signal-'transmitter has operated totransmit the fire-signal, which signal may bethe identitication Vnumber five times repeated, in conjunction with differentiating signalimpulses between each repetition. The apparatus and circuits used for the manual firesignals willalso be as Well supervised, and receive the same benefits therefrom and in a. similar way, as is the case with the circuits and devices heretofore described.

To annunciate the tire-signals locally so as to visually indicate from which signal-station they are sent, and to cause bells to be sounded and lamps to be lighted throughout the building, in case of ltire means are provided which are vhere shown as arranged in connection with the relays b5, and the parte are so constructed and varranged as to be operated by the armature-levers of said relays b only in case of fire, said armaturelevers being free to respond to other signals Without aiecting the operation of the annunciating-means. i

Referring to Figs. l, I7 and 8, y represents the annunclator controlling-magnet, which is included in the branch .circuit-wire d, s o as to be energized only When the relay am is operated in response to the operation of a lire signaling-device. y2 represents separately-pivoted annunciator-dro-ps arranged above the armature-levers of the relays b5. An arm ya is -arranged beneath each annunlciator-drop, and said arms are designed to engage and hold the annunciator-dro s in elevated position. Said arms are fixe to a rock-shaft g4, so that,A when said shaft is rocked, all of said varms will be moved from beneath the annunciator-drops to permit said drops to fall a short dist-ance and engage the upper ends of the armature-levers of their respective relays b5. An arm y is fixed to said rock-shaft `and engages the upper end of the armature-lever y, of the controllingmagnet 1 and, when said lever is moved by the attracting-armature, said arm y will be disengaged and permitted to fall. As the ire ,signaling-devices operate said rela s b5,

it will be seen that in case any of sai signailing-devices are operated, the annunciatorcontrolling magnet y will be operated, and the relay corresponding to the tire signalingdevice Which is operated` Will attract its armature, and the annunciator-drop which is in engagement with the armature-lever of said relay will be released and permitted to fall. A latch y is also fixed toV the rockshaft g4, which normally engages a springacting member y? of a switch which is adapted to control an alarm-circuit ys, which, as here shown, may contain electric-'lamps and bells. This switch is normally held open but is unlocked andfree to operate to close upon operation of the rock-shaft. llt will thus be .y
